Win11 feels like a half built facade placed over the Win10 interface. For example, to compress a file from the right click menu you have to click "show more options" which just switches to the Win10 menu. Also, moving away from text in context menus and replacing with an inconsistently formatted icon only menu is an assault on the user IMO.

I don't feel like saying plasma 6 or gnome is cherry picking. Plasma, at least to me, feels very polished. The theme management is incredible, diverse, and easy too. I feel it's better aesthetically out of the box, but with negligible effort a theme can be installed to exceed commercial competition.

Windows 10 felt decently fleshed out and very clean, but often you still had to use the old control panel and other menus.

Android is clean and polished but limiting in customizability. Android UI apps seem to break completely every couple updates until the maintainer patches. There's no consistency between devices/manufacturers either.

I haven't used an Apple product since 2006 so i can't speak for those.
